Material

Ordinary carbon steel: economical and practical, suitable for inland waterways and short-distance vessels Q235B, Q345B

Alloy steel: high strength, low temperature resistance, preferred for polar ships 40CrMnMo, 35CrMo

Stud Stainless Steel Anchor Chain : seawater corrosion resistance, offshore platforms and special ships 316L, 2205 duplex steel

Strength

K3 grade: basic grade, breaking strength ≥410MPa, suitable for small fishing boats and river barges.

K4 grade: medium-high strength, breaking strength ≥ 690MPa, mainstream choice for commercial cargo ships and offshore engineering vessels.

K5 grade: ultra-high performance, breaking strength ≥860MPa, special for deep-sea drilling platforms and military ships.

Marine Stud Anchor Chain

Surface treatment

Hot dip galvanizing: zinc layer thickness ≥85μm, salt spray test over 2000 hours, low cost and comprehensive protection.

Epoxy resin coating: chemical corrosion resistance, suitable for oil platforms and other highly polluted waters.

Solvent-free spraying: environmentally friendly process, in line with IMO PSPC standards, reducing marine pollution.

Relevant Standards

ISO 1704: The authoritative specification of the International Organization for Standardization for anchor chain dimensions, tolerances and test methods.

ABS (American Bureau of Shipping), DNV (Det Norske Veritas), LR (Lloyd's Register) and other classification societies certification, covering K3, K4 and other high-strength grades.

GB/T 549-2017: China's national standard for inland and offshore vessels.

JIS F 3301: Japanese Industrial Standard, emphasizing anti-corrosion and anti-fatigue properties.
